„ Trigonometric / Inverse-Tri. Functions

The calculator provides standard trigonometric functions and inverse
trigonometric functions - sin, cos, tan, sin

–1

, cos

–1

and tan

–1

. See

Example 35~37.

(Note) : When using those keys, make sure the calculator is set

for the angle unit you want.

„ Hyperbolic / Inverse-Hyp. Functions

The calculator uses [ 2nd ] [ HYP ] to calculate the hyperbolic
functions and inverse- hyperbolic functions – sinh, cosh, tanh,
sinh

–1

, cosh

–1

and tanh

–1

. See Example 38~39.

(Note) : When using those keys, make sure the calculator is set

for the angle unit you want.

„ Coordinates Transformation

Pressing [ 2nd ] [ R

P ] displays a menu to convert rectangular

coordinates to polar coordinates or vice versa. See Example
40~41.

Rectangular Coordinates

Polar Coordinates

x + y i = r (cosθ+ i sinθ)

(Note) : When using those key, make sure the calculator is set

for the angle unit you want.
